Caching issue

Hi,

This is to do with the accordian menu control in ajax Since you use ajax internally for the telerik contraols, I thought of asking this question to you.

I show and hide a menu item in the accordian menu based on a dropdown selection. The problem is that I have refresh the page to show/hide the link and I can track down this to caching or viewstate issue. Is this sometime you can help with?

Thanks

Thank you for help...

Tooltip not showed correctly

I have a list of data that displayed in RadGrid. When mouseover the label, the tooltip shown. For the first load, the data in the tooltip is loaded correctly. When navigate to another set (by clicking the "Next" button in the demo below), then mouseover to the same position, the tooltip is loaded but the data is not correct.

What do i need to change so that the tooltip can be loaded correctly.

Below is the sample code that can produce this issue.

Thanks in advance.

Open Table Property Page, which throw the error

We have recently upgrade to the new version of the telerik.Web.UI control (2010.2.713.35) from the old version (2009).
However, once we open the table property page, it throws the error message "The ToolName property must be set!

Below is the piece of the code, we make the content editor with the EditorTools.
EditorTool tool = new EditorTool(ep.FunctionName);
toolGroup.Tools.Add(tool):

The rest Editor tool works fine such like Hyberlink manager, image manager ect.

In addition, we try to assign the tool.Name at code level, unlucky, it will still throw the same error.
